Sostantivi Numerabili e Non Numerabili

• Countable nouns are nouns that can be counted and have a plural form.
• Uncountable nouns (also known as mass nouns) cannot be counted and typically do not have a plural form.
• Articles (a, an, the) are used differently with countable and uncountable nouns.

Countable Nouns

• Can be singular or plural
• Singular countable nouns can be preceded by the articles "a" or "an" (indefinite articles) when referring to something non-specific or when first introducing it.
• Plural countable nouns can be used alone or with the article "the" (definite article) when referring to something specific.
• Examples of countable nouns: book, car, apple, student, house

Uncountable Nouns

• Always treated as singular.
• Typically do not take the indefinite articles "a" or "an".
• Can be used with the definite article "the" when referring to something specific.
• Often refer to substances, concepts, or collections.
• Examples of uncountable nouns: water, air, advice, information, furniture, sugar

Articles: A, An, The, or No Article

• "A" and "an" are indefinite articles, used to refer to a non-specific or general countable noun. "A" is used before words that begin with a consonant sound, while "an" is used before words that begin with a vowel sound.
• "The" is a definite article, used to refer to a specific noun that has already been mentioned or is known to the listener/reader.
• No article is used in the following cases:
  • Plural countable nouns when referring to something in general.
  • Uncountable nouns when referring to something in general.
